Best Practices in the Generation of a Coal Resource Estimate.

Most critical to the success of a mining development is a reliable Mineral Resource Statement that underpins the Ore Reserve.

There is considerable evidence from technical studies that project failure is more often than not down to poor geological practices and the resultant inadequate Mineral Resource estimation.

A reliable Mineral Resource estimation combines good quality and relevant data, competent geological interpretation and a sound methodology. From this data is and its interpretation, it will be possible to generate a reliable representation of the mineralised deposit, its geometry, grade distribution and variability and its density. Mineral deposits are unique and the generation of a Mineral Resource Statement that complies with an International standard, such as the JORC code, signed off by a competent person, is an important part of the reporting process.

This gives a potential investor confidence that prescribed procedures incorporating best practices have been followed.
